The utility model relates to the technical field of plate-fin heat exchangers, in particular to a plate-fin heat exchanger welding end socket which comprises a shell, a header pipe is welded to the top face of the shell, a sieve plate is installed on the lower portion in the header pipe, second baffles are welded to the two sides of the bottom of the sieve plate, and second springs are connected to the outer sides of the second baffles. The tail end of the second spring is connected with a first baffle, and a hinge is installed between the first baffle and the sieve plate. According to the screening device, when the first baffle rotates to be perpendicular to the screening plate, the first baffle and the screening plate can be fed into the main pipe, and after the first baffle and the screening plate are fed into the main pipe, the screening plate continues to be moved downwards, so that the first baffle and the second baffle enter the shell; at the moment, the first baffle can be unfolded under the elastic a
